If Bellinger has another decent year in 2025, I think he is much more likely to opt out next time to sign a multi-year deal going into his age 30 season. He wasn't going to beat the $27.5M the Cubs are going to pay him in 2025, but he would probably be willing to give up 1 year of $25M in exchange for a long term deal. Of course if he gets hurt or regresses further in 2025, then he would opt in again, but hopefully that isn't an issue.
